Describe: This OLED display module is small, measuring only 0.96 inches diagonally, and it consists of 128 x 64 individual yellow and blue OLED pixels, each of which is turned on or off by a controller chip. It works without a backlight, i.e. in a dark environment, the OLED display is higher than the LCD display. You'll love the sharpness of the thumbnails. The driver chip of this OLED is SSD1306, which is IIC communication. So this module can be controlled by I2C. That is, in addition to VCC and GND, if 4-wire I2C mode is used, 2 wires are required. There is also a simple switched capacitor pump that converts 5V to low voltage drive for OLEDs, making this module the easiest way to integrate OLEDs into your projects.
